CaptainI was flyng the pmdg 744 at flight level 310 running about 95.6 percent RPM when I climbed to Flight level 350 I was averaging 100% RPM now even though my engine is running at a higher RPM will the fuel consumption be less (even in flight sim 9)?

Chief CaptainI wouldn't have a clue but I think range comes into consideration, so depending on what range your flight is 😉
CaptainTrue however I've seen qantas 744 at Klax before and I've attempted the same trip with the pmdg 744 with undesirable results

Try the Posky model and see what happens 😉
Chief Captaintrick question...
the air is thinner at FL350 than at FL310.
Thinner air= higher RPMs
CaptainBut less fuel burn I assume?
CaptainI dunno if im right or wrong here but i thought pilots of heavy aircrafts like 747 i thought if thay go higher lets say FL350 or FL400 that saves them more fuel for there trip.
Chief CaptainFrom what i hear yes Morris... we should ask CRJCapt... he would know best.

Yes 😉
First OfficerDoes your FMC not give you an optimum flight level Karl?
That should be the level at which you burn the least amount of fuel...
And even if not, when you're at - say - FL350, you can still check the fuel flow rate and your GS, then climb to FL390 and check fuel flow again, but maintain same GS.... that should give you the answer.. 🙂
